Purple stems on some seedlings?

Why would the plants on that edge of the tray have purple stems? Nutrient deficiency? I noticed the one I checked with a purple stem had more roots showing from the rockwool cube than any others... think they're trying harder to get to the juice cause they got shorted?

Purple stems can be a sign of an issue but if they look healthy it's more likely an awesome genetic trait in my opinion. 🤘😤
